i have a glscene project. In the sceneviewer i import some stl files as freeform. The user can interact with this objects (move and rotate them with mouse). Now i have to export this whole scene to one stl file, so the position and the rotation of the freeforms should be like in the scene after this export ("merge"). I found this thread here
about a similar problem, i tried this, but this creates an broken stl file (tried open with meshlab).
I hope there is some idea for creating a solution. If somebody knows a solution for another 3d-file format, it will be great too.
